__d··on Professor denounces mass AI fraud on an exam at Brown
I would often do a bullet point summary/outline of my answer on the paper. That would have arrows and insertions and crossed-out stuff everywhere -- it was usually a mess.

But then I'd use that to write the actual text answer, and consequently, it was mostly clean. I'd still have to cross stuff out or add a phrase between the lines every so often, but once the basic structure was done, that was mostly unnecessary.

And if I was ever pressed for time, I'd usually get part marks for the outline anyway. Depending on the subject, I'd sometimes race through the questions doing just the outlines, and then come back to write the full text as a complete second pass.

To be fair, this wasn't creative writing. I think it'd be harder when the expression is the content.

__d··on Professor denounces mass AI fraud on an exam at Brown
My child's high school is doing the same thing: all exams are now handwritten on paper in a supervised room. Phones and smartwatches are always banned during the school day, but laptops are banned during exams. This is standard at state-funded high schools in Australia.

There will likely be a period where those who went through high school with computers struggle with hand writing stuff, but the next generation will have done it all their lives.

__d··on No-One Escapes the Permanent Underclass
The fun part is that this all plays out concurrently with our destruction of the Earth’s climate.

That permanent underclass might easily end up a lot smaller than you think.

And then you think … maybe that’s not coincidence?

__d··on No-One Escapes the Permanent Underclass
Yes. But. I imagine the others did not fail to learn from this.
__d··on Lore – Open source version control system designed for scalability
Try gitolite?

https://gitolite.com/gitolite/index.html

It has fine-grained permissions but works with regular git clients.

Shoot the messenger. That’ll fix it.
__d··on Ask HN: How to live life before AGI
The concept of a "job" can encompass many things. Some of those change when machines become more capable, some don't.

For example, one part of a job is the satisfaction, the purpose, the meaning of life derived from being useful. Not having that can be pretty bad for people. So, even if the machines take over a lot of what is done by people today, you'll probably want to find a way of being useful.

Hedonism and wealth are both remarkably bad at delivering the same contentment that being useful does. That said, of course, a bit of hedonism and capital is also good.

__d··on I work in Hollywood. Everyone who used to make TV is now training AI
> let them run for a season/series and gauge popularity vs cost, and cut the under performers (why I don't watch a show until a couple seasons are live).

And so you don’t contribute to the selection of shows.

It’s a dilemma. I started streaming stuff I like the sound of despite the risk of being rug-pulled, because otherwise there’s no signal that they should fund series 2.

__d··on I bought Friendster for $30k – Here's what I'm doing with it
If I could afford that I wouldn’t need a social media app.
__d··on I bought Friendster for $30k – Here's what I'm doing with it
I have a heap of family and friends who live in a different country to me. I'd love an old school Friendster / early Facebook-style social medium where we could share posts, but the tapping mechanic makes this impractical for me.
__d··on An AI agent deleted our production database. The agent's confession is below
I’m sorry to be harsh but this is 100% your fault, and attempting to shift the blame onto Cursor and Railway just doesn’t fly.

The onus is on you to make sure your system uses the APIs in a way that’s right for your business. You didn’t. You used a non-deterministic system to drive an API that has destructive potential. I appreciate that you didn’t expect it to do what it did but that’s just naivety.

You’re reaping what you sowed.

Best of luck with the recovery. I hope your business survives to learn this lesson.

__d··on How NASA built Artemis II’s fault-tolerant computer
Helpful video, thanks!

At about 1:20, the presenter says the BFS uses a different OS and hardware (not sure if that means a different instance, or a different class, so to speak).

__d··on How NASA built Artemis II’s fault-tolerant computer
Yeah, that was my guess too but the comment about separate implementation for the backup system made me wonder if there was a different OS, and the which was running where.
__d··on Show HN: A WYSIWYG word processor in Python
This is great!

Curious about the choice of toolkit: what led you to wxPython?

__d··on How NASA built Artemis II’s fault-tolerant computer
Does anyone have pointers to some real information about this system? CPUs, RAM, storage, the networking, what OS, what language used for the software, etc etc?

I’d love to know how often one of the FCMs has “failed silent”, and where they were in the route and so on too, but it’s probably a little soon for that.

__d··on Germany Power Prices Turn Deeply Negative on Renewables Surge
Yes. Europe has far more wind than Australia, I imagine for that reason.
__d··on 10 Enduring Lessons from Adam Smith
What is the purist’s solution to eg. polluting rivers or air or soil in pursuit of one’s own enrichment?
__d··on Germany Power Prices Turn Deeply Negative on Renewables Surge
It’s a daily event now in Australia. Very low prices during the middle of the day, and higher in the morning and evening. Anyone with a battery or an EV they don’t need to drive far can play the market, usually with scripted sell/buy trigger points.

There’s enough profit to make the payback period for a decent battery quite short.

__d··on Germany Power Prices Turn Deeply Negative on Renewables Surge
They would find it hard to compete with negative prices too.
__d··on My son pleasured himself on Gemini Live. Entire family's Google accounts banned
One difference to something like email is that you can change search providers with minimal effort. There’s no server-side context to back up or migrate, no third parties involved: you just use a different URL.
__d··on LG's new 1Hz display is the secret behind a new laptop's battery life
I’m not an expert here, but …

CRTs needed to be refreshed to keep the phosphors glowing. But all screens are now digital: why is there a refresh rate at all?

Can’t we memory-map the actual hardware bits behind each pixel and just draw directly (using PCIe or whatever)?

__d··on 4Chan mocks £520k fine for UK online safety breaches

Let's say they did. Would you be saying "So what?" then too?

The people living there might struggle to identify the difference?
__d··on 4Chan mocks £520k fine for UK online safety breaches
I've been hearing that since the 1990's when it first started to become apparent that their economy was on track to overtake the rest of the world within a few decades.

It hasn't happened yet. Is there something you perceive as especially problematic now, as opposed to the last 30 years?

__d··on Wayland set the Linux Desktop back by 10 years?
From one perspective, the XLibre folks seem to be taking the Perl5 path, and hoping Wayland is Raku.
__d··on Wayland set the Linux Desktop back by 10 years?
I wouldn't say "mentally unstable", but zealous is probably fair.

To create something like the GNU project, or OpenBSD, or Linux, takes serious levels of commitment. You really have to believe in it, and to a degree, you have to _will_ it into being. Along the way, you need to explain why your crazy idea is worth all the sacrifice, discourage those who would distract your team members, maintain your own and the team's focus through years of not actually having the thing you want in any useful form, etc, etc. You have to be an unreasonable person to take it on, and then continue it.

There are people who become "fans". They can be even more zealous than the project leader(s). Maintaining direction (aka control) of a horde of over-zealous fans takes aptitude and patience. It's easy, I think, for projects to devolve into vitriol, and denigration of those who think differently, even if it starts out from a good place.

All group endeavors are ultimately political. A group endeavor with a multi-year payoff period and no tangible rewards? It's bound to be very political.

That said, we all enjoy the fruits of their labors ...

__d··on Wayland set the Linux Desktop back by 10 years?
Disclosure: I'm not intimately familiar with all this.

I think Perl5 was originally planned to be replaced by Perl6. Then Perl6 took much longer than anyone expected, and kinda ended up in a different place. Perl5 was re-anointed as the once-and-future Perl, and what had been Perl6 became Raku.

If I remember correctly, somewhere in the middle of all that there was talk of running Python (and other languages) on the new Perl6 VM.

So, compare this with say the Python2 to Python3 migration.

Similar motivations: the developers had some legacy decisions that were unfixable without breakage. But they were sick of it, and decided to just go for it.

Most end users didn’t care about those issues. The few that did were happy to pay the cost of switching. Everyone else clung to Python2 for years because migrating was high cost and low value.

It took about 15 years to complete the migration for most, and there are a small number of users who will never make it over.

Perl5 to Perl6 is another useful historical example.

FOSS development is managed by the developers, and so, compared to a commercial software project, the implementation issues get more weight. This sort of thing is very likely to happen again and again.

__d··on Boy I was wrong about the Fediverse
It would be nice to have a server that supported arbitrary domains. Perhaps https://jointakahe.org/ would suit?

OTOH, eg. (not an advertisement, just the first search result) masto.host offers managed Mastodon hosting for $6/month, which is on par with eg. Fastmail or Proton's base non-free plan.

__d··on Boy I was wrong about the Fediverse
Unless I'm missing something, that's exactly the same.

If you're using someone else's email domain (like, eg. gmail.com), you cannot migrate to another provider. If you use your own domain, you can change who is hosting it.

Like email, there are plenty of Mastodon hosting companies. You can use your own domain, and migrate between them at will. If you use eg. mastodon.social, you can even migrate in most circumstances (but not if the instance vanishes).
